 We know that in most circumstances that there are two outs in an inning and somehow a fielder gets a ball gets the ball and he's able to quickly tag out two runners that That's not technically a double play because as soon as the the first one first runner is tagged out That would be the third out in the inning and then the next guy is really irrelevant to the situation He would not be so the fourth out that wouldn't carry over to the next inning But whenever it comes to appeals there are there is a few situations where the umpire and it can actually acknowledge Or under the rules of the game they would acknowledge something called the fourth out And so there's quite a few different ways because obviously it's there's a different quite a few different possibilities Situations that are possible to to to have an appeal play so But let's just look at one and see how this fourth out could possibly Come into play So let's say for this example. We have the bases loaded Runners on first second and third base And that there are two outs in the inning And and with two outs Our batter here he comes up to the plate and He hits a line drive single Hard hit ball out to center field So with two outs That means that all the runners are moving right away So this runner on third base he runs home and he scores No problem this The runner on second base. He's going to to run and he's gonna touch third. He's gonna round third And he's going to be coming home. And while he's doing that He's center fielder out here. He's going to pick up the ball Never catch her in here and so and so Because the the the single was so hard hit the center fielder He's gonna pick up the ball and he's going to throw it into the catcher The catcher is going to catch the ball and he is going to tag out This second runner here this runner who originally started on second base and So he's going to To tag out this runner and that would be Presumably the third out in the inning however While this is going on We had this runner here who started on on first base and Whenever he was he was coming around Second base he actually for whatever reason he stepped over second base. He did not touch second base He came over but he made it the whole way to third base and Then the the the batter of course he would he would have run up. Maybe he just waited on first base So what we have here is this runner who started on third base He ran home and he scored one run no problem And then because this runner who originally started on second base was thrown out It seems like he was he was the third out in the inning So we have one run in and we have three outs. However, if the defense realizes they were They were paying attention and they they know the rules They can can appeal this play here this The runner who started on first base that stepped over second base and did not touch it because remember You know here that if a runner Misses a base that's legitimate grounds that the defensive team can appeal so So maybe the second baseman he says wait a second To the to the maybe the catcher still has the ball. He says hey throw me the ball We're gonna appeal this play the second baseman gets the ball Steps on second base appeals to the umpire says we feel that this runner Stepped over second base and then continued his way on to third base and in that situation because this is a force out on the appeal that means that the run would not count because it is the Third out in the inning and so we would have three outs We would have no run score and and and the inning would then be over Because the the defense then they could elect to to take that It would be the Quote-unquote fourth out in the inning and so so that is where that can come into play
